Optimal power saving scheduler for 802.11e APSD
A new system and method is described, utilizing a scheduler based on a transmission power consumption calculation and prioritizing algorithm. The system utilizes the (APSD) protocol specified in the 802.11e draft for saving power in wireless local area networks. The system comprises an access point having a priority queue, one or more stations, an APSD frame comprising an association ID for identifying one of the stations and a scheduled wake-up time for the identified station. An algorithm is employed for calculating the total transmission power consumption of downlink data for the stations. The AP originates and transmits to the one or more stations the APSD frame of the scheduled activation delay time. The current data to be transmitted to each station is accessed by the algorithm to determine the total transmission power consumption to each station. A priority queue in the AP is ordered from the lowest to the highest receiving power consumption, assigning the highest priority to the lowest power consumption transmission to minimize total power consumption to the PS stations in the AP queue.

Communication device with a self-calibrating sleep timer
The present invention provides for a system for operating a communication device (20) for reception of scheduled intermittent information messages (22) with a dual mode timer (70) that extends battery life. A controller (50) schedules the timer (70) to power down all idle components of the device (20) between message receptions in a power saving sleep mode to conserve battery power. During active mode when the device is fully active in reception of messages, the timer (70) uses a reference oscillator (90) with a relatively high frequency to support digital processing by the receiver (26). During sleep mode when only the timer is powered on, a much lower frequency sleep oscillator (96) is used to maintain the lowest possible level of power consumption within the timer itself. The timer (70) has provision for automatic temperature calibration to compensate for timing inaccuracies inherent to the low-power low-frequency crystal oscillator (96) used for the sleep mode. The resultant improvement in timer accuracy during sleep mode eliminates the need for an initial reacquisition period following wake up in active mode, thereby reducing battery drain in active mode as well.

PFC-PWM controller having a power saving means
InactiveUS6839247B1Stable deliveryImprove transmission efficiencyEfficient power electronics conversionConversion with intermediate conversion to dcSwitching signalEngineering
A PFC-PWM controller with a power saving means is disclosed. A built-in current synthesizer generates a bias current in response to feedback voltages sampled from the PWM circuit and the PFC circuit. The bias current modulates the oscillation frequency to further reduce the switching frequencies of the PWM signal and the PFC signal under light-load and zero-load conditions. Thus, power consumption is greatly reduced. The PFC and the PWM switching signals interleave each other, so that power can be transferred more smoothly from the PFC circuit to the PWM circuit. The saturation of the switching components can be avoided by limiting the maximum on-time of the PWM signal. Further, an external resistor is used to start up the PFC-PWM controller and provide an AC template signal for PFC control.

System for power savings in server farms
ActiveUS20070130341A1Energy efficient ICTMultiple digital computer combinationsBiological activationPower management
A threshold-based approach is used to assign tasks to servers in a server farm. A “number of connections” count or “connection rate” is maintained for an active server and when the count achieves a first value a wake up signal is sent to a next (inactive) server to alert the inactive server to become active and periodic keep alive signals are initiated. When the number of connections next reaches a second, higher value, subsequent requests for connections are sent to the newly active server. Variations of this approach allow for servers and their associated processes and devices to be handled in clusters for power management scaling efficiency. Servers can be placed in the inactive mode when the number of connections reaches a lower threshold. Other criteria can be used to determine activation of servers, processors or other devices or processes. Other types of resource use monitoring can also be used with this invention.
